...according to Mr. Walmsley himself, strongly resembles an earlier draft of Cthulhu Dark. Basically I added:
A Harm stat, for combat
Skills to differentiate characters' abilities beyond their occupation.
Target numbers and difficulty
Simple rules for Magick
from the Introduction:
I developed these rules to meet the needs of my specific play group. There are two main issues with Cthulhu Dark that I will attempt to address:
A realistic, intuitive mechanic for Harm as well as Insanity. (Rolling with your current Insanity as the target number is neither.)
Mechanical differentiation between characters, based on their particular skills.
I have reprinted nearly all of the rules from Cthulhu Dark with my own additions, so this document should represent a playable game. I have removed all examples for the sake of brevity. No infringement on Mr. Walmsley’s copyright is intended.
